After running fine for over a year unraid suddenly started crashing randomly. I thought it was connected to me upgrading to the 6.10 version, but downgrading did not solve the problem.

 

The problem is that unraid reboots/crashes suddenly after running between 5min and a couple of hours. This is what I have tried:

 

• Removed UPS
• Removed GPUS
• Updated Motherboard BIOS
• Disabled VM engine
• Removed SSD cache from array
• Disable docker engine
• Migrated to a new USB-key and started over from scratch
• Runned memtest for 12 hours

 

If I boot the server directly into windows 11 without running unraid I can run both gpu and cpu stress test for hours without any problems.

I am completely out of ideas now. As I understand it should not be any hardware-problems as I can run windows barebone without any problems.

I just purchased a new usb and started fresh from that one without restoring any settings. I restored the array and started downloading a few dockers through the "appstore" but after I finished configuring a couple of dockers the system crashed again.

 

Does anyone have any ideas of what the problem can be ?

Have you looked at the power settings in this thread.

It's not the RAM speed rating that matters, it's the motherboard / CPU memory controller that matters.

 

Are you running the RAM at the approved speed for your CPU? It's likely several steps lower than the RAM rating.

Yes and yes.

RAM is rated at 2800Mhz but is running at 2133Mhz and that is lower than the max spec from here: ram speed

I have now tried clearing CMOS settings on my motherboard and tried:

 

Global C-States  = Auto

Power Supply Idle Control = typical current idle

Booted up and server runned fine for a couple of hours then crash/reboot

 

Changed bios settings again to:

Global C-States  = Disabled

Power Supply Idle Control = typical current idle

Server crashed again after a few hours.

 

But if i skip unraid I still can boot it directly to windows without problems and it never crashes from gaming or any other activity.

After changing the USB, PSU, motherboard and switching out the RAM I finally found what caused the instabillity, it was the Ryzen 3900x CPU. I just replaced it with a 5600G while the 3900x is beeing replaced.

So now everything is almost back as it was before. Only problem is that I now have really poor performance in my windows 11 VM even tho I have assigned it the same amount of cores.
